I To all who-mat may concern."

Be it vknown that I, PHILIP MUELLLER,

"a citizen ofthe United States, residing at Decatur, inthe county of Macon and State of Illinois, have invented new and useful Improvements in Socket-Heads for Curb- Cocks, of which the followingis a specification. y y

This invention relates primarily 'to a socket head for curb cocks, but it may also be used onany part requiring to be turned by a removable key or equivalent implement.

The object of the invention isto'provide the turning plug of atiicock. or. other part to .be turned with an integral or detachable socket member so arranged that when a key of the proper shape is inserted in the socket to turn the. plug, if there be any.accumula-.

'tions of dirt or other matter-in the socket,

the end of the key when inserted, will force such accumulations out of the socket through suitably disposed openings at the bottom thereof. These openings may be of any number, shape, and size desired to permiteasy escape of the accumulations.

I*urthern1o're, the openings prevent water collecting in the socket and, in cold weather, freeze and break the socket member.

The socket head of the present invention, in its detachable form, may be made with a polygonal shank or a polygonal socket to bedetachably, connected, respectively, to a plug or other object having a similarly shaped socket or projecting stem.

The following detail descriptionof the invention will, for the sake of clearness, be confined to its application to curb cocks, it is to be understood however that the claim is intended to cover the structure broadly and for all uses to which it is adapted.

In the accompanying drawing -Figure l is a vertical sectional view of the invention in its detachable form applied to a socketed cock plug. Fig. 2, a similar View slightly modified showing-the socket head detached from the'cock. Figs. 3 and. 4:, plan views partly in section of Figs. 1 and 2 respectively. Fig. 5, avertical sectional viewof thetype of socket head illustrated in Fig. 1

.modified to fit 'a' cock plug formed with a polygonal projecting head or stem, and Fig.

6,4.a, vertical sectional VIEW of 'a socket head cast-integral: withthe turning plug.

In the drawings, in which like reference characters are used forthe same parts inv all a projecting head or stem 13 shown "iniF cock and 11 its turning plug suchfas' a common use.- The plug 11 may have a socket 12 in upper end. as in Fig.

'. 5. The numeral 14 designates the socket-pi ad forming the subject matter of this in ention, from the bottom of which a stem 15, see Figs. 1 and 2, prov1ded a plurality of angular ribslS, preferasly four in number, to engage the corners of the socket 12 of the turningplug which is generally square in cross-section. The socket head is retained in place by a bolt 17 threaded in thelsocketed extension of the plug 11 and bearing against a flattened surface on one of said angular ribs.

. The modifiedform" of .the'socket head represented in; Fig. 5. is provided with -a square socket 18 in its underside to fit over the square head'l3 of the, plug 11, and is aflixed thereon by a pin seated in registering holes in the head 13 and the lower end of the socket head 14.

The socket head 14 is formed with a chamber or socket 19 extending downwardly for a suitable distance from its top, the lower part of which chamber or socket is preforably of circular, and the-upper part- 20 of polygonal, cross-section, preferably square to receive the squared end of a suitable op-v crating key. If desired, the chamber or socket 19 may be of polygonal cross-section throughout its -length. The sides of the polygonal part-2O fiaremore or lessfroi'n above downwardly, there being an out-waul bevel at the top to assist in centering i. 1. key. Through the'walls of the socket head 14 at the bottom of the 1 chamber 19 are openings 21, two being shown in Figs. 1 and 3 and four in Figs. 2-and 4, The number openings, however, is optional. The floor 22 of the chamber 19 inclines from-the -ce:-i-

ter of the chamber toward the openings 2 3-,

the bottoms. 'of said openings being continuous with said .floor. The tops also, as well asthe sides of the openings preferably flare outwardly as in Figs. 1, 3 and 4.

' F-rom" the abovedescription, and an inspection of the-drawings, it will benotedthat the. chamber or socket 19 gradually enlarges from .itsupper end to its floor 22,

owing to the flaring sides of the polygonal portion, the circular portion of said chamber has a} greater diameter than the distance bethe figures, It) indicates the body 'of aeu'rb 1 to be applied to finished cocks, but in Fig.

6 is shown a turning plug ll -with a socket head 14 formed integral therewith, the socket head proper being in all respects-the same as that shown in the preceding figures with two, vfour or any desired number of openings 21. In this form of the device the 7 socket head will be lower or nearer the turning plug 11* because of the omission of the socket 12 'or the head or stem 13 from the plug.

The openings 21 may vary both in sha e and size to any extent desired, Figs. 2' ancf 6 showing circular openings, while Fig. 5 shows rectangular openings of'greater Wil 11 than height. In Fig. 1 the openings 21 are made both wide and high, in fact, they may be as great or greater in area than the upper polygonal part 20 of the socket 19 sothat any article, such as a pebble, a piece of stone, or a piece of brick falling through said upper end can be pushed outward through one of said openings.

A device of the character described comprising a socket head having a cylindrical chamber therein and a polygonalpassageway connecting said chamber to the upper end of the socket to receive a turning member, said passageway increasing in width .from above downwardly and of less crosssectional area: at any part thereof than said chamber, said chamber having a plurality of passagesopening outwardly therefrom in lateral directions, increasing in size as they progress, the floor of said chamber inclining from the center thereof toward each lateral opening and being continuous with the lower side of the opening.
